8 Claims.

This invention relates to safety razors, and particularly to a safetyrazor blade holder adapt- .ed for cooperation with a relatively rigiddoubleedged blade.

.5 One;object of the invention is to provide in a safety razor a holderof unitary construction, that is to say, one in which the parts of theholder need not be disassembled in order to re-" move the bladetherefrom or to reverse the position of the cutting edges of the bladerelatively thereto.

, Another object of the invention is to provide a .blade holder ofsuchconstruction that when its blade holding parts are loosenedrelatively to 5 one another, the inherent resiliency of these parts willresult in automatic ,unclamping of the blade regardless of the positionof the holder, so that the said blademay be easily removed.

A further object of the invention is to pro- 20. vide, in combinationwith a relatively rigid double-edged blade, a holder element so formedthat, when the blade is clamped in a shaving position relativelythereto, both cutting edges of the blade will lie in close proximity tothe holder element, 5 one of same in position for shaving, and the otherin a position protected by the holder element.

Another object of the invention is to provide a razor holder ofrelatively few parts and of such simple construction that it may bemanufactured at low cost and with an economy of material; it being,nevertheless, of a practicalanddurable construction.

A still further object of this invention is to V provide a safety razorin which the upper surface thereof is relatively free from markedprojections to thus permit ready shaving or the 'upper lip, forinstance, and in which the blade is so held as to preclude chattering.

With these objects in View, the invention contemplates a safety razorcomprising a blade holder, and a blade for cooperation therewith, theblade holder including a guard member, a back member and a handle, theguard member and Q5 back member being'permanently and fixedly connectedand capable of resilient relative movement, the back member providedwith'blade clamping means extending through the guard member, whichlatter is apertured to receive them, and the handle so cooperating withthe guard member and back member as to impart relative movement theretoto clamp the blade between them by virtue of the cooperation of theblade clamping means with the blade and with the guard member; and theinvention contemplates, further, various details of construcexplainedhereinafter tion of the parts mentioned, all as will be moreparticularly and finally claimed. a J

Referring particularly to Figs. 1, to 5 inclusive and 1 0,'it will beseen that the razor blade holder of the invention comprises a guardmember 1, a back member 2 and a'handle 3. The guard mem ber l ispreferably provided adjacent to one of its edges with guard teethiand isapertured, as indicated at 5, for passage through it :of bladeengagingmeans 6 preferably formed integral with the back member 2 and havingblade-clampingportions '7, shown in the form of hooks overlying aportion-of the guard member. The guard memher is also provided with ashield member; 8 ,here- 0 inafter more particularly referred to. I a

The back member, inthe form of the invention illustrated in thefiguresjust mentioned, is provided with means, preferably in the formoflugs 9 for engagementwith complemental means such as the slots .10 inthe guard member, whereby by heading over'the lugs 9, as shown, theguard member and the back member may be riveted together to providebetween them a fixed connection of such a nature as to permit theirrelano tive resilient movement.

formation and the relative arrangement of its cutting edgesand the edges16" of its apertures face-contacting or toothed edge of the guard membermay lie closely thereagainst, and that its opparallel alignmenttherewith, the blade, no matter receive the screw threaded extension 13of the handle 3, this screw threaded extension preferably having its end14 so formed as to furnish it with a good bearing for engagement withthe under face of the guard member 1.

Theblade 15 which, as hereinbefore mentioned, is of substantially rigidconstruction and of the double edged type, is apertured as indicated at16 to provide for the passage through it of the bladeengaging means 6,and has offstanding from its ends lugs 17 by means of which it may bereadily grasped. The apertures 16 are, as shown in Fig. 5, of somewhatgreater longitudinal extent than that of the engaging means 6, so thatthe blade may readily be engaged with and disengaged from the engagingmeans. However, in order that the blade may be properly positionedlongitudinally of the guard member, the edges 16 of the apertures 16'adjacent to the'ends of the blade are spaced apart a distancecomplemental to the outer edges of the engaging members 6. s

In order that, when clamped against the guard member, the edge of theblade adjacent to the not being used may be shielded, so that it may notcut the fingers or face of the useror other things which might come incontact with it, the

shield member 8, which stands above the upper surface of the guardmember, is provided.

It will be apparent from the foregoing that the blade is assembled withthe holder simply by arranging it with its apertures 16 passed over thesecuring means 6 and its'cutting edge adjusted relatively to theface-contacting or toothed edge of theguard member by pushing itrearwardly of the guard member until the edges 16" of the aperturesadjacent to the blade edge to be used are stopped by the members 6, andthen screwing up the handle so that the end 14 of its screw threadedextension 13 firmly presses the guard member,

, and with it the blade, against the hook-like portions 7 of theblade-securing means 6. In order to remove the blade from'the holder,all that is necessary is to unscrew the handle slightly, whereupon,because of the resiliency of theguard member 1 and back member 2, theguard member and the blade with it will move away from the hook likeportions 7 of the blade-securing means 6, and the blade may be removed.

It is to be noted that, due to its double-edged adjacent to thesecutting edges, and which are in which of its edges is to be used, iscapableof proper positioning relatively to the skin contacting edge ofthe guardmember teeth formed therein.

In all functional characteristics the modified and to the guard form ofthe holder illustrated in Figs. 6 and 7 is 'the same as that justdescribed. However, in this Also, instead of merely rounding the uppersurfaces of the guard teeth as shown in Figs. 1 to 4 inclusive, theguard teeth 4 of the guard member 1 are rounded by bending down orcurving the edge of the guard member in which they are formed. Theblade-securing means 6 and their hook-like members 7 are substantiallythe same as those previously described, as are also the handle 3' withits screw threaded extension 13 engaging screw thread 12' of the sleeve11*. The end 14.! of the extension 13 is of slightly different formationfrom the end 14 previously described, but will function just asefficiently.

In this form of the invention the shield member 8 is formed upon theback member 2 rather than upon the complemental guard member.

In the modified form of the invention illustrated in Figs. 8 and 9, theguard member 1 and the back member 2 are integral, and the shield member8 thereof forms the flexing connection at which the resilient actionbetween the member 2 are passed through the apertures 5 and arethereafter bent to form the hook por- 'tions 7 The guard teeth 4 areformed in a manner similar to the guard teeth 4 of Figs. 6

'and 7, and are similarly curved.

The handle 3 and its screw threaded extension 13 and the parts 11 and 12of the back member are formed in substantially the same manner as thecorresponding parts of the modification illustrated in Figs. 6 and '7.

It is to be noted, that the apertures 5 of the guard member 1are'relatively somewhat larger than those of the forms of the inventionin which the guard member and back member are made as separate elementsand united, for the reason that sufiicient clearance must be provided topermit appropriate bending of the portions of the guard member whichform the blade securing means 6 and their hook portions 7*.

From the foregoing description, it will be seen that the inventionprovides -a holder for doubleedged blades which not only need not bedisassembled for the purpose of removing the blade or of reversing theposition of its cutting edges, but one in which the blade-securing meansautomati- -cally separate to free the blade so that it may be removedfrom the holder as soon as clamping pressure is released.

It will be apparent, also, that the holder, due to the simplicity of itsconstruction, may be easily manufactured at relatively low cost.

Various changes'and modifications are considered to be within the spiritof the invention and the scope of the following claims.
